Measure the voltage, current and power. The PF is power/(volts x amps).
The formula you are looking for is kW = I x E x pf/1000 for single phase and kW = I x E x 1.73 x pf/1000 for three phase.
The formulas you are looking for are, single phase kW = I x E x pf/1000. For three phase kW = I x E x 1.73 x pf/1000.
In exactly the same way as you do so for a single-phase load. It's the product of the power of the load, expressed in kilowatts, and the during of operation, expressed in hours. (And the symbol of kilowatt hours is 'kW.h', not 'kwh')
The power factor is a measure of the phase difference. If they are exactly in phase the PF = 1. If they are 180 degrees out of phase PF = 0.
The motor cannot be altered to work on single phase power. You will either have to put in a new single phase motor or use a phase convertor box. Do a google search for phase convertor - you will find plenty.
You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com
Because the voltage is 208 I will assume that it is the 3 phase formula you are looking for. Amps = Kw (430) x 1000/1.73 x Volts (208) x pf. Unless you know the pf use .9 and you won't be to far off in the calculation. Same formula for single phase but don't use 1.73.
Assumption: F= 60Hz V= 1v is equal also to I=1amp. PF= 0.85 Single Phase: Three Phase: S = IV pf / 1000 S = 1.73 x I x V x PF/1000 = 1 x 1 x 0.85/1000 = 1.73 x 1 x 1 x 0.85 /1000 S = 0.00085KVA S = 0.0014705KVA
In order to draw the phase diagram for transformer operating at load with lagging PF and leading PF, you will need to know the equation for the transformer being load free. This constant will help you with the load bearing equation of Np/Ns=Vp/Vs=Is/Ip.
Single phase.
Yes, there is a difference between single phase and three phase circuits.
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
